A top to bottom GPU refresh

Nvidia today splashed the mobile market with more than half a dozen new GPUs comprising the company's GeForce GTX 800M Series. This is a top to bottom release, meaning the new GPUs range from entry-level (GeForce 830M) all the way up to what Nvidia claims is the fastest mobile graphics chip in the world, the GeForce GTX 880M. The new releases join Nvidia's already available 820M GPU.
